论文摘要
我们提出了一种可以隐藏对象和来源的抛物线热（以及质量或光扩散）方程的主动掩盖方法。通过Active，我们的意思是它依赖于在要掩盖的区域的边界上设计单极和偶极热源分布。从热测量的角度来看，可以将相同的技术用于使源或对象看起来像遮盖区域外的观察者。我们的结果假设具有均质的各向同性大量培养基，并且需要了解斗篷或模仿的来源，但在大多数情况下，与斗篷的对象无关。
We present an active cloaking method for the parabolic heat (and mass or light diffusion) equation that can hide both objects and sources. By active we mean that it relies on designing monopole and dipole heat source distributions on the boundary of the region to be cloaked. The same technique can be used to make a source or an object look like a different one to an observer outside the cloaked region, from the perspective of thermal measurements. Our results assume a homogeneous isotropic bulk medium and require knowledge of the source to cloak or mimic, but are in most cases independent of the object to cloak.
